Pressurizing an Expansion Tank on Boiler — Heating Help
Open the boiler drain valve and drain out water until the gauge reads 12-15 psi. Repeat putting air into the tank as before. Stop adding air when the gauge doesn't show any increase in pressure. That means that there isn't any more water in the expansion tank to expel. Set the tank pressure to 12-15 psi. Open the boiler cold water feed valve.

Boiler Water - an overview | ScienceDirect Topics
Maintaining the pH of boiler water in the range of 9–11 decreases the rate of corrosion; 9.2 to 9.8 is ideal. In low-pressure steam or hot water heating systems, nitrite or chromate provides a protective film on metal surfaces. Filming amines provide a physical barrier to protect metal from corrosion. They are effective in the pH range of 5.5
